No users or groups returned from LDAP server

No users or groups were found on the specified server. This warning is issued when a base
DN with no users is specified in the Base DN field, or the user
specified in the Authentication DN does not have sufficient
privileges to query the contents of the LDAP tree. Update these fields on the Configuration > System > eDirectory page, and click Verify Settings again. Additionally,
increase the time limit on your eDirectory server, if it has run out.
